Microchip Technology Inc. has unveiled the MCP2036 analog front end (AFE) for inductive touch-sensing applications.

Complementing the company's royalty-free mTouch Inductive Touch-Sensing solutions, the fully integrated MCP2036 AFE works with almost any 8-, 16- or 32bit PIC microcontroller or dsPIC digital signal controller, making it easy and cost effective for designers to enhance user interfaces with inductive touch-sensing technology. This inductive-touch AFE includes a mux, a frequency mixer, an amplifier, a driver, and a voltage reference, which the company says lowers component count, and reduces design size and cost. Additionally, the AFE can be easily configured for a variety of applications in the appliance, industrial and automotive markets.

The MCP2036 AFE is available in a 16-pin, 4mm x 4mm QFN package, as well as 14-pin PDIP and SOIC packages. Pricing starts at $0.33 each in 10,000-unit quantities. Samples and volume-production quantities are available.
